Land use is considered as a major interface between socio-economic and environmental processes (Letourneau et al 2012).Land use occurs in local places,considered a local environmental issue generally,but it is becoming a force of global important.Activities of land use have transformed a large proportion of the planet's land surface,mainly for acquisition of natural resources to meet immediate human needs at the expense of environmental conditions (Foley et al 2005).Since the "land use and cover change" (LUCC) science plan was proposed together,land-use change has become the front and hot point task of the global change and many projects and studies have focused on LUCC (Turner et al.1995, Lambin et al.1999,Lambin et al.2001).For recent decades,researchers have tried to simulate land-use changes at different temporal and spatial scales,with different geographical models and for different purposes (Li et al 2002a,Matthews et al 2007, Verburg et al 2008, Schweitzer et al.2011, Verburg et al.2011).The favored techniques for implementing model of spatial dynamics is cellular automata (CA) (White et al.2000).
